1 Inside the Earth

2 TOC: Earths Layers 2/27/12 I.Starter: Calculate the Speed of an object traveling 120 miles in 3 hours. Next, calculate the time it would take the object to get 240 miles if it traveled at that same speed. Show your work!!!!

3 Practice: Record all notes and demo observations in your practice section.

4 The Earth is broken up into 3 main layers o Crust - lithosphere & asthenosphere o Mantle – upper, middle, & lower o Core – inner & outer

5 The Crust Outer layer km thick 2 types of crust Oceanic (very dense, made of basalt) Continental (less dense, made of granite)

6 Oceanic and Continental Crust

7 The Mantle Middle layer Very thick layer

8 The Core Made mostly of iron 1/3 of the earth’s mass Very hot

9 Earth’s Layers How are the earth’s layers similar to an egg? Shell=crust Egg white=mantle Yolk=core

10 Earth’s Layers How are the earth’s layers similar to an orange? Peel=crust orange slices=mantle center=core

11 Earth’s Layers How are the earth’s layers similar to an apple? Peel=crust Inside of peel=mantle Apple core=core

12 Although the Earth has 3 Main Layers - it can be further divided into these layers: Lithosphere Asthenosphere Upper Mantle Middle Mantle Lower Mantle Outer Core Inner Core

13 Physical Structure of the Earth (5 Layers) Lithosphere- crust and upper most solid mantle Asthenosphere- solid rock that flows slowly (like hot asphalt)- Convection happens here! Mesosphere – upper, middle & lower mantle Outer Core- liquid layer Inner Core- solid, very dense Mantle

14 III. Application: Tape in both the Layers of the Earth Foldable and the Layers of the Earth Vocab Foldable

15 Connection: - Draw the below chart and complete with detailed answers Compare and Contrast the Layers of the Earth and Sun Earth layersSun LayersSimilaritiesDifferences Crust Photosphere Asthenosphere Convective Zone Mantle Radiative Zone Core

16 IV. Exit: Summarize in 7 sentences what you learned about gravity. Explain how the demos demonstrated Gravity. Be Descriptive!!!!!
